Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures. Teaching is suplemented by practical laboratory work.

Assesment methods and criteria linked to learning outcomes

Final classification reflects the result of continuous check in the form of tests in the seminars. The final examination consists of the obligatory written test and facultative oral part.

Aims

The goal of the course is to inform students about the fundamental laws and theories of classical and modern physics and to train them to apply this knowledge to simple physical systems, to explain and predict the behaviour of such systems. Further goal is to expose physics to students as the theoretical basis and fundament of engineering disciplines.

Specification of controlled education, way of implementation and compensation for absences

Attendance at seminars and labs which are stated in the timetable is checked by the teacher. Absence may be compensated for by the agreement with the teacher.
